he radius of the base of a cylinder is 10 centimeters, and its height is 20 centimeters. A cone is used to fill the cylinder wit

Elis [28]

Volume of cylinder: $V_{\text{cyl}}=\pi r^2h$ , where $r$ is the radius and $h$ is the height. This volume is $\pi\times10^2\times20=2000\pi$ (cubic cm).

Volume of cone: $V_{\text{cone}}=\dfrac13\pi r^2h$ , with the same variables denoting the same parameters. This volume is $\dfrac13\pi\times5^2\times10=\dfrac{250}3\pi$ (also cubic cm).

The number of times it would take to fill the cylinder with water using the cone as a source would be

$\dfrac{2000\pi}{\dfrac{250}3\pi}=24$

The volume of a pyramid is 240 cubic centimeters. The pyramid has a rectangular base with sides 6cm by 4cm. Find the altitude an

Leni [432]

Answer:

altitude = 30 cm

lateral surface area = 301 cm² (approximately)

Step-by-step explanation:

let the altitude be x,

240=6*4*x/3

or, x=30 cm

Lateral surface area,

=l×√(w/2)²+h²]+w×√[(l/2)²+h²]

=6×√[(4/2)²+30²]+4×√[(6/2)²+30²]

≈300.99806

≈ 301 cm²
